Effect of Mineral or OFMSW Digestate Fertilization on Ryegrass and Nitrogen Leaching

The current guidelines of waste management are aimed at the recovery and recycling biowaste while respecting protection human health environment. recent European legislation on fertilizers provides for use digestates derived from organic fraction municipal solid (OFMSW). objectives this study were to verify fertilizing effect three types OFMSW ryegrass culture comparing mineral fertilization evaluate nitrogen lost leaching in soil diversely fertilized following simulated rainfall. was grown pots. with fertilizer or digestates. For each treatment, five mowing procedures performed crop, biomass production concentration determined samples. During experiment, six rains simulated, leached analyzed. results showed that: (i) nutrition similar ammonium sulphate fertilization, confirming agronomic validity these by-products reduce synthetic fertilizers; (ii) had a positive limiting loss due compared highlighting soil-improving properties by-products, particular composted digestate.
